• Full threading along the entire 1-1/4" length delivers maximum grip strength and pull-out resistance
• Precision compatibility with No. 21 drill bits (0.159" diameter) for accurate hole preparation and installation
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing applications

Professional Applications & Engineering Value

These No. 10 TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications where traditional fasteners often cause material stress, cracking, or insufficient holding power. The tri-lobe shank design combined with thread forming technology creates strong, permanent threads in plastic materials without generating chips or debris. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining the necessary strength for durable fastening. The Phillips flat head configuration with standard profile ensures flush mounting in countersunk applications, making these thread forming screws ideal for electronics enclosures, automotive plastic components, and consumer products where reliability and aesthetics are critical.

Specification Summary & Compliance

These inch-system tapping screws feature precision No. 10 thread diameter (0.19") with 14 threads per inch and right-hand threading. The TRS (Thread Rolling Screw) design follows industry-standard thread forming principles with fully threaded configuration. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The flat head design incorporates standard 82° countersink angle for proper seating in prepared holes using No. 21 drill bits.
